As the title says i want to make some images in QtDesigner.
I used QMainWindow with QMenu, QToolBar, QScrollArea and QStatusBar.
I want the quality to be as best as possible.
OS: Ubuntu 22.04
Fault Print screen attached:
The problem is with the QScrollArea.
Edit: There is no problem if i use pyuic5 command first to compile the .ui files to .py files

I have created a conda environment (say, called 'ds0') and installed some packages (e.g., python, pandas etc.). I then in vscode set the interpreter to be the one which I just created. I expect I could have my code working propery in the conda environment in vscode.
but then I have a problem, when I use the interactive mode in the ipynb file, I cannot import the packages,
e.g.,
import pandas as pd
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-11-f9ebee165770> in <module>
----> 1 import pandas as pd
ModuleNotFoundError: No module named 'pandas'
other code in the ipynb is running properly (e.g., to print a message etc.).
so it looks like vscode in the interactive mode is not using the right environment - but I did set the environment as 'ds0', and also if I save the ipynb file as a python script(e.g., as 'test1.py'), I can actually run it and vscode does recognize the pandas package.
so, how can I fix the issue so that I can run the code properly in the interacrive mode (e.g., in ipynb file).
** this is macbook m1 laptop, I just have the latest anaconda and vscode installed. I also tried to create additonal conda environments and the isse is the same. I am not sure if there is a problem with the ipykernel.
Thanks you!
I now have a solution to the problem - though I do not quite know if what I found was the culprit.
What I did and what did NOT solve the problem:
I installed ipython, ipykernel in the vscode terminal and the conda terminal (may be duplicated) manually - what happened was that, if I create a new ipynb file, I can select the both the interpreter and the kernel properly, and the code runs perfect - but if I open the previous ipynb file, I still have the problem - it looks like vscode is using different kernels for two different ipynb files
What I did: I reinstalled the Mac OS Big Sur (this may be unnecessary though) and I installed a clean miniconda and vscode - however this does not solve the problem. vscode still does not use the right kernel (but it looks like it uses the right interpreter/env which I created via conda). It looks like vscode is not using the right kernel (the icon in the upper right hand side suggests that the jupyter server local is 'disconnected'), also it puts a warning msg saying 'invalid version -final'
What I did and what DID solve the problem:
Then I deleted all the existing ipynb file and re- cloned from Github. this solves the problem - but I do not know why and how it solved the problem.
In the top right corner, you can see the name of the kernel used ("Python 3.8.1 64-bit: Idle", for example). Click on that, and select the kernel you want to use. That's how I fixed the problem. The Kernel is named within the ipynb file, and if there's a mismatch between that and your system, the notebook will not run.
I have much trouble to have a code to convert pdf file to png on python 3.6, windows 10.
I know what you are going to say : google it !
But barely everything I've found was on python 2.7. And some packages haven't been updated.
What I've seen so far it's that the best way to do it is using Wand, right ? (I have installed ImageMagick before )
from wand.image import Image
# Converting first page into JPG
with Image(filename='0.pdf') as img:
img.save(filename="/temp.jpg")
# Resizing this image
Here was my second error :
wand.exceptions.DelegateError: PDFDelegateFailed
`The system cannot find the file specified.' # error/pdf.c/ReadPDFImage/809
So i read i need ghostscript. I installed it. But the package is for python 2.7 and it doesn't work. I found python3-ghostscript 0.5.0. https://pypi.python.org/pypi/python3-ghostscript/0.5.0
New error :
RuntimeError: Can not find Ghostscript DLL in registry
So here I needed to install Ghostscript 9 :
https://www.ghostscript.com/download/gsdnld.html
First of all it's not a GPL license ... That's not even a package but a program. I don't know how I can use it in my futures python codes...
and there is still an error :
RuntimeError: Can not find Ghostscript DLL in registry
and i can't find anything for it.
Ghostscript is licensed under the AGPL, the licence can be found in /Program Files (x86)/gs/gs9.21/doc if you want sources then they are available from the Ghostscript Git repository. Note I'm assuming you are running on Windows since you refer to the Registry.
If you install the prebuilt binary then it will create an entry in the Windows Registry, I assume that's what your Python code is looking for but I can't be sure. You should make sure you install the correct word size (32 or 64) version required by Python, if it cares.
You can, of course, simply run Ghostscript to render a PDF file and produce PNG output.
gswin32c -sDEVICE=png16m -sOutputFile=out%d.png input.pdf
This will create one file per page of the input PDF file, use gswin64c for the 64-bit version...
You can alter the resolution of the output with the -r switch, eg -r300
I presume you can simply fork a process from Python. Otherwise you'll have to get someone to tell you what the Python script is looking for in the Registry. Perhaps its looking for a specific version of Ghostscript, or the 32-bit version or something.
I've upgraded my deveolpment environment from python-3.2/ Qt-4.8/ PyQt4 to python 3.4.2 / Qt5.3 / PyQt5.
Everything is Ok but the python source code generation with pyuic5.
When calling this commands I get the error
/usr/bin/python3: No module named uic
The Qt uic program is located at
~/Qt/5.3/gcc_64/bin/uic
The PyQt5 pacjakge is located at
/usr/local/lib/python3.4/site-packages/PyQt5
Even if the PyQt5 environment is operational as runtime I can't build any new GUI interface, so I can't move forward with this application upgrade.
Any idea ?
Thanks for help.
Thanks for the answer from #Akhil. The code below really helps me avoid the "module not found" problem, and successfully create a .py file from a .ui file.
exec python -m PyQt5.uic.pyuic youruifile -o yourpyfile -x
call python -m PyQt5.uic.pyuic -x filename.ui -o filename.py
this one worked for me (28th june 2017, PyQt5, python 3.6, win10, 64bit)
I faced the same issue. I had installed PyQt into a virtual environment and the issue was the the pyuic5 script was not using the python interpreter for that virtual environment.
So I opened up the pyuic5 script
exec pythonw2.7 -m PyQt5.uic.pyuic ${1+"$#"}
to
exec python -m PyQt5.uic.pyuic ${1+"$#"}'
This resolved the issue for me.
I know this is late, but I just recently encountered this issue when setting up external tools for Qt Creator. I know its not exactly what you ran into but it produces the same error. I don't like the idea of modifying files in my anaconda/bin directory so I didn't want to implement either of the other answers.
What I did find is that when you are setting up an external tool Qt Creator operates as if you are working in a new environment (i.e. your PATH is not the same as your development path). What I found is that you need to set the Environment field to have the same path as your development environment. This occurs by default when you setup Build and Run Settings for your project, but not for external tools.
Like #ekhumoro said in his comment You must pay attention to your PATH at all times.
I believe you are a Mac user and I had faced a similar issue.
It seems you'll simply have to provide the full path of the pyuic file (for me, it was under a hidden folder usr in the home directory: /usr/local/Cellar/pyqt/5.10.1_1/bin/pyuic5).
In your terminal, change directory to where the *.ui files( which you wish to convert to a *.py file) lies.
So for instance, if you have a Qt designer file saved by the name untitled.ui on your desktop, put in the following command in your terminal:
Amars-MacBook-Pro:Desktop amaradak$ /usr/local/Cellar/pyqt/5.10.1_1/bin/pyuic5 -x untitled.ui -o untitled.py
Hope this helps...
Cheers
Try this: i've been searching for 2 days and all problem solved!
First Rule in Python: Don't use .XML this is not Java instead use .PY for me i don't need uic at all
Let's begin, my pyuic5 actually there is no in PyQt5 folder instead in Scripts Folder
C:\......Python\Python37-32\Scripts\pyuic5.exe
you have to make sure that the yourFile.ui is in the same location of your pyuic5.exe
Follow the pict below, you will be understand:
How to convert ui to py for easy way
uic not found solved
it works like a Charm !
Hi everybody , see last pict, i just converted ui to py for the first time in my life !
What is the application used by canopy when running a python file?
This application opens in a new window when using matplotlib. See screenshot below.
Is it possible to use this application directly without canopy?
Matplotlib opens a displays a figure that has been rendered by the selected backend when you call show. You can find out what backend is in use with:
matplotlib.get_backend()
and set the backend by updating the matplotlibrc file or with:
matplotlib.use('PS')
matplotlib.use() has only effect if called before pylab, matplotlib.pyplot, or matplotlib.backends is imported for the first time.
Running the same Python program with the same backend in an environment other than Canopy will display the same figure.
The application that displays the plot is Python (in particular Canopy User Python), using the Matplotlib library with a Qt backend. To run this from outside Canopy:
1) Ensure that Canopy User Python is your default Python; the simplest way is to open a "Canopy Command Prompt Window" from the Start Menu, or see https://support.enthought.com/entries/23646538-Make-Canopy-User-Python-be-your-default-Python).
2) Run the following commands:
set ets_toolkit=qt4
python my_scripty.py
How do I install uncrustify? I followed the instruction to install uncrustify but when I run it, it does not work. Can anyone give me some help installing this tool? I want to run it on objective-c code in xcode 4. Thanks in adavance
On OS X Mavericks 10.9.1 :
1- to install brew, open a terminal windows and type :
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
It will ask you to download some other files, answer OK for all (for more information see : http://brew.sh/index_fr.html).
2 - to install uncrusify, open a terminal windows an type :
brew install uncrustify
3 - to make your code beautiful, download BBUncrustifyPlugin-Xcode available at https://github.com/benoitsan/BBUncrustifyPlugin-Xcode
You will just have to :
compile the project
copy the file uncrusify.cfg in your home directory
restart Xcode.
NB : With BBUncrustifyPlugin, you don't need to use Automator.
4 - After restarting Xcode, use the menu Edit > Uncrustify Selected Files to uncrustify the selected items in the project navigator.
Your code is now beautiful! That's magic!
post-scriptum : You can easily change your uncrusify configuration file by using :
https://github.com/ryanmaxwell/UncrustifyX
http://universalindent.sourceforge.net (better in my case)
I hope that this will help!
I setup Uncrustify with Xcode 4 like so: http://blog.carbonfive.com/2011/03/10/code-formatting-in-xcode-4/
Can you explain what you tried to do, what you expected to happen, and how it didn't work?
Download zip
On Windows, download the latest version of Uncrustify here: https://sourceforge.net/projects/uncrustify/files/latest/download
Extract zip
The program is a standalone exe, so just extract the downloaded uncrustify-...-win32.zip file anywhere. For this example, I'll use C:\Uncrustify. So, the uncrustify.exe would be in that directory.
Add directory to PATH System Environment Variable
In Windows 7+: Type Winkey + env - Select "Edit the system environment variables"
On the Advanced tab, click the Environment Variables button at the bottom.
In the System variables section at the bottom, click the Path variable, then click the Edit... button.
Click the New button, and type C:\Uncrustify, or the directory that you extracted uncrustify.exe to.
Important: Click OK to close the dialog boxes or your change will not save.
Verify
In a CMD window, typing where uncrustify should return the path to the uncrustify.exe.
In my case it shows C:\Uncrustify\uncrustify.exe
Close Atom and reopen it. Now you should be able to atom-beautify and it will use Uncrustify to format your selection
